The Government Accounting Office (GAO) has issued a 51-page report examining the challenges the Department of Defense faces in developing and fielding new positioning, navigation and timing (PNT) technologies to complement, augment or replace GPS when it is unavailable. It found that the DOD is not doing enough in this regard.

Iridium Communications Inc. made a strategic investment in DDK Positioning (DDK), an Aberdeen, Scotland-based provider of enhanced GNSS accuracy solutions. DDK uses the Iridium network, provided by a low Earth orbit (LEO) constellation, to provide global precision positioning services that can augment GNSS accuracy

Multi-antenna carrier-phase differential GNSS (CDGNSS)-based pose (position and orientation) estimation aided by monocular visual measurements and a smartphone-grade inertial sensor form the core of a system designed for micro aerial vehicles. It can be applied generally for low-cost, lightweight, high-accuracy, geo-referenced pose estimation.
The year 2020 was definitely one for the history books. The global pandemic forever changed life as we know it, and in its midst, our GPS development and production teams launched us deep into a new era of positioning, navigation, and timing (PNT) capabilities.
